[SIPForum-discussion] Prefered audio codec

[Fredrik Sandedal]

Hi,

 

Could someone give me suggestions on the best audio codec to use when
DTMF is necessary and the bandwidth must be kept on a low rate?

 

I heard that there could be problems with DTMF and G729AnnexA but I
haven't been able to do any advanced test with this.

 

Regards,

 

Fredrik Sandedal, Enera
